SYLVANIA SJK3C300 (SJK-3-C-300) is a three-pole molded-case circuit breaker from the SJK family, rated for 300 A and designed for 480 VAC three‑phase service. As an MCCB, it provides overcurrent protection by interrupting fault currents in distribution panels and feeders, acting as a disconnect device in commercial and light‑industrial installations where reliable 480 VAC protection is required. The 3P, 300 A configuration makes it suitable for protecting feeders and branch circuits in systems that operate at 480 VAC, with a rugged molded housing designed for panel mounting.
